Jd 7520 losing prime

jelfert · Jul 10, 2017

My 7520 has been losing prime as the fuel level in the tank goes down. Does anyone have a diagram of the internal tank fuel lines? Where are the bleed screws on the fuel injection pump?

I would say you have a check valve sticking or just bad. Friend had same thing with his and would let fuel bleed back to fuel tank.

Also, what style hand primer does it have? I've replaced every one of mine with the the spring-loaded bosch kind.

do you know anything about the hydraulics on the 7520?
